Patrick Klepek (Giant Bomb)
When Patrick Klepek isn't breaking big news stories, he's probably tweeting about Lost, horror movies, Lost, Chihuahuas, football, beer, and Lost. Really, though, Klepek is one of the best journalists in the business.
He goes for the throat in terms of research, talks to plenty of sources, and regularly gets more information than most can dig up. He's also got crazier, cooler hair than most everyone on the planet, and it deserves its own Twitter ID.
